Somebody please help me?​
Natalija [7]

The events A and B are independent events, and the values of P(A) and P(B) are 7/12 and 1/2, respectively

<h3>The value of P(A)</h3>

The event A is given as:

A : Sum greater than 6

In the sample space of a roll of two dice, there are 21 outcomes that are greater than 6, out of a total of 36 outcomes

This means that:

P(A) = 21/36

Simplify

P(A) = 7/12

<h3>The value of P(B)</h3>

The event B is given as:

B : Sum is divisible by 2

In the sample space of a roll of two dice, there are 18 outcomes that are divisible by 2, out of a total of 36 outcomes

This means that:

P(B) = 18/36

Simplify

P(B) = 1/2

Hence, the probability values of P(A) and P(B) are 7/12 and 1/2, respectively

Please help me I suck at math ​
Firlakuza [10]

Answer:

1

Step-by-step explanation:

To find the slope of a line, you need to find how much it rises for a certain amount of run. Here, the line rises from -3 to 1, which is a rise of 4, while "running" from -1 to 3, or a run of 4. 4/4=1. Hope this helps!
